MD69BC BEARING CIRCLE FOR BEARING COMPASS REPEATERS

DESCRIPTION

The MD69BC is a traditional vane type Bearing Circle. It allows an observer to take a bearing of a distant object by aligning the two sighting vanes with the object. The near vane contains a peep sight while the far vane contains a vertical sighting wire. A diametric horizontal wire from the near vane to the far vane enables the observer
to read the bearing from the Compass Repeater card. A reflector vane positioned behind the far vane allows the observer to observe azimuths of luminous celestial bodies (stars and planets) at various altitudes by picking up their reflection in the black mirror. When the body is observed, its reflection appears behind the vertical wire in
the far vane. The MD69BC is supplied with a removable shadow pin which indicates the azimuth of the sun by the direction of its shadow. The instrument is finished in a semi-gloss black paint to complement other external marine navigation equipment and is supplied in a wooden instrument box. The MD69BC Bearing Circle from Marine Data: flexible in application, easy to use and simple to maintain.
